2:27 and He shall rule them with a rod of iron, as the vessels of the potter are broken to pieces, as I also have received authority from My Father;
and He shall rule them with a rod of IRON as the vessels of the potter are BROKEN to PIECES
The strong rule with a rod of iron also comes from the Messianic Psalm 2. The image of a broken pottery is equated to rejection of the word of God several times in the Old Testament. Isaiah uses it in Isaiah 30:12-15. Jeremiah shows this act as a symbol of condemnation of this rejection in Jeremiah 19:10-13 where not only the rejection is bad but the people worshipped other gods!
as I also have received AUTHORITY FROM MY FATHER;
So to the overcomers, the coming reign of the Messiah will be shared with true believers under the authority from the Father. See Revelation 1:5, Revelation 3:21, Revelation 20:6, and 1 Corinthians 6:1-3.
